FRANK G. STUOKEL, 0F RAGINE, WISCONSIN, ASSIGNOR TO 3'. I. CASE THRESHING MACHINE COMPANY, OF RAOINE, WISCONSIN, A CORPORATION.

KEY-REMOVER.

Specification of Letters Patent.

Patented Aug. 31, 1915.

To all whom it may concern:

Be it known that I, FRANK C. STUOKEL, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Key-Removers, of which the following is a specification.

My invention relates to an improved device for removing keys from shafts and the like, whereby I am enabled to securely grip and maintain a positive hold upon the key while withdrawing the same, and which consists in certain details of construction and arrangements of parts as will be hereinafter more fully described.

In the accompanying drawing, which forms a part hereof, Figure 1 is an underside plan of my improved key remover; Fig. 2 a side elevation thereof, and Fig. 3 a detail sectional View as seen when looking in the direction of the arrows from the dotted lines 33 in Figs. 1 and 2.

In said drawing, the portions marked 5 indicate the handle, which may be of any suitable proportion and preferably tapered, and terminates in a head-piece, 6,formed with shoulders, 7, at each side, and with a groove, 8, in its under side. In said shoulders I mount the jaws, 9, 10, preferably made of tool steel, and secure the same by pivot pins, 11, 12, each of said jaws having a comparatively sharp, inturned gripping edge, 13, 14, and so enlarged, as at 15, to lie in a plane with the working side of the head-piece 6, as indicated in Fig. 3, so that the tool may lie in parallel relation to the shaft from which a key is to be extracted and thus be in convenient position for the operator to exert a straight and powerful pull upon the key. Each jaw is mounted in said head-piece independently of the other, and at its rear end carries a set screw, 16, for a purpose which will hereinafter appear.

In operation, the jaws of the tool are brought about the end of the key to be wlthdrawn, or if it is of a character where it 1s deslrable to grip it beyond the end, the grooved portion of the head-piece is laid over the key, which permits the jaws to extend downwardly at each side thereof. Each of said screws 16 is then adjusted with a wrench or otherwise to draw the ends of the jaws firmly and tightly against the key, which insures a positive unslipping grip thereon, so that the operator, by pulling upon the handle, may readily withdraw a key from its seat.

I claim as my invention:

1. A key remover, comprising a handle, a head-piece thereon having oppositely disposed shoulders and a longitudinal groove in one side between said shoulders, and adjustable jaws mounted in said shoulders.

2. A key remover, comprising a handle, a head-piece thereon having oppositely disposed shoulders, and adjustable gripping jaws mounted in said shoulders and enlarged on one side to extend to the plane of said head-piece.

3. A key remover, comprising a handle, a head-piece thereon having oppositely disposed shoulders and a longitudinal groove in one side between said shoulders, and adjustable gripping jaws mounted in said shoulders and enlarged on one side to extend to the plane of the grooved face of said head-piece.

In testimony whereof I affix my signature in presence of two Witnesses.

FRANK O. STUCKEL.
